colocar opção ao passar o mouse parar a transição

salve meninos e meninas...

não entendo de JS mas preciso de que ao passar o mouse no meu slider o mesmo pare com a transição, e ao tirar o mouse de cima volte a funcionar..

este é meu script, mas não sei criar a função ou parametro para o mesmo..
